ED'VVARD G. BACKIVIAN, OF YOUNGSTOWN, OHIO.

SASI-I FASTENER.

Application filed April 3, 1925.

This invention relates to fasteners, the object being to furnish an economical, efficient and easily operated joint automatic locking device for the two opposing sashes of an ordinary window, so adapted and applied as to hold both sashes in any relatively adjusted, fixed, vertical position.

In the drawings accompanying these specifications, Figure 1 represents a side view of my device, including a fragmentary view of each sash, showing its application,

Figure 2 is a top plan view, also including a fragmentary view of each sash, showing its application.

Figure 3 is a top plan view of the holding bar.

Figure t is an edge view of the holding bar.

Figure 5 is a top plan view of the plate or base which is attached to the top of the upper cross member of the lower sash.

Figure 6 is a side or edge view of the plate.

Figure 7 is a side view of the operating and locking lever.

Figure 8 is an edge view of the lever.

Similar reference characters designate corresponding parts of the invention throughout the various figures of the drawings.

S represents the lower sash and S the upper sash. Secured. to the upper cross member of the lower sash S, by means of screws 1, is the plate 2, carrying on its inner edge the bifurcated upstanding bracket 3, and on its outer edge the oppositely disposed ears 4-4. Swingingly mounted between the ears 44:, by means of pin 5, is the holding bar 6, which may be provided at its free or swinging end with an increased width, as at 7, to insure a firm grip upon the face of the upper sash without marring the surface. 01 if preferred, this inner end may be provided with a covering of some non-abrasive substance, such as rubber or felt. T he holding bar 6 is provided with a central longitudinal slot 8 for the purpose hereinafter indicated. Swingingly mounted in he bracket 3. bv means of pin 9, is the operat mg and locking lever 10, provided at its lower end with the arm 11 disposed at somewhat less than an angle of 90 degrees (right angle) to the lever proper. and adapted to engage the lower face of the holding bar-6 when the lever is forced inwardly or towards the sash. The lever 10 passes through the Serial No. 20,406.

slot 8 in bar 6, and is provided on its edge adjacent the arm 11 with a series of holding notches or teeth 12, designed to engage the upper face of bar 6, as at 13, to hold the latter securely locked in firm engagement with the upper sash.

The operation of my device is as follows:

Assuming that the two sashes are locked in closed position, the operator would simply press the lever 10 inwardly, which will disengage the teeth 12 from the holding bar 6 and at the same time cause the arm 11 to move upwardly into engagement with the lower face of the holding bar 6, thus forcing the swinging end of the latter out of engagement with the upper sash,all as shown in dotted lines, Figure 1, when. the sash may be adjusted to any desired position, after which the lever 10 is drawn forward, causing the outer end of the arm 11 to move downwardly, and thus permitting the holding bar 6 to move downwardly by gravitation into engagement with the sash, and with the same movement of the lever forward the teeth 12 of the lever will engage the upper face of the bar 6, thus holding it securely locked.

I claim? 1. In a sash fastener, a base plate, a hold ing bar swingingly mounted upon one edge of said base plate, an operating lever swingingly mounted upon the opposite edge of said plate and carrying an oif-standing arm or member adapted to come in contact with said holding bar when said lever is forced inwardly, said lever being also adapted to fasten said holding bar in operative position.

2. In a sash fastener, a base plate, a hold ing bar swingingly mounted upon one edge of said plate and provided with a central longitudinal opening, an operating lever swinginglv mounted upon the opposite edge of said plate so as to extend upwardly through the opening in said holding bar and carrying an off-standing arm or member adapted to come in contact with said holding bar when the lever is forced inwardly, said lever also being provided with a series of holding notches or teeth on the edge adjacent said oif-standing member and adapted to engage said holding bar to fasten it in operative position.

In testimony whereof I hereunto affix my signature.

EDWARD G. BACKMAN.
